How to exclude subfolders from the backup?

Bohuslav, welcome to these public User Forums.

Unfortunately there is no method of excluding sub-folders by using the Exclusions options for a Files & Folders backup task (that I am aware of or could find!).

If folders have been selected in the Source selection panels, then they cannot be excluded using Exclusions!  If they are not selected in the Source options, then they do not need to be excluded!

I can only suggest submitting Feedback direct to Acronis about this requirement - you are definitely not the only person who has asked for this capability.

Any attempt to set Exclusions using such as *\obj\* immediately disappears as soon as you press Enter to save the exclusion!

Hello Bohuslav,

I've added your request as a vote for the existing feature request (the internal ID for ref TI-160100 Support wildcards for folder type exclusions when making a Files & Folders backup). Thank you!

For example subfolders like:

• obj
• debug
• release
• TestResults

There is a way to do this but it is risky if one don´t know the pitfalls. I have had similar needs, iow the need to exclude many subfolders and specific file types.

For example, if you want to exclude Folder A you can add it to the Exclusions tab as per the attached image. This will exclude Folder A and all it´s content and it´s subfolders when running a backup. 

The great thing is that it works and the thing to be aware of is that all folders named Folder A in your backup will be excluded. So if the name Folder A is used on five different places in your project none of them will be backupped. This will be a problem if you want only one (1) of them excluded.

So, by adding *obj* and *debug* and *release* and *TestResults* will work, but be aware of that all instances of the specified folders abowe in the backup will be excluded, in this case obj, debug, release and TestResults. That may or may not be a problem.

Thanks for sharing the above Roger.

...good tools to quickly check how many and which folders would get excluded are Everything (www(.)voidtools(.)com/) or Ultrasearch Free (www(.)jam-software(.)de/ultrasearch_free), both freeware.

K, found my personal workaround - a bit of a PITA but works:
One can 1st select the whole folder/drive and then has to manually unselect any file/folder (that is not to be backed up) in the backup source selection tree (one can 'walk' the tree).

HTH!

@ Acronis: bug: Partially selected drives/folders appear exactly the same as fully selected ones
